Faces and Exceptions

Hi all,

So I'm reworking part of the forge search error handling to deal with
throwing meaningful SSL messages (see my previous message). My goal so
you can step back and tell me my approach is completely wrong: I want
to capture SSL verification failures so I can tell a user that the
OpenSSL CA bundle needs work basically. I originally went to just add
another Puppet.err output in the puppet/forge/repository.rb part, but
then I stopped and realised I should be really just raising exceptions
here so higher levels can display the output - my wariness comes from
the fact that I want to see Puppet::Forge more as an API for general
usage - and avoid assumptions at that level about how the consumer
wishes to display errors. So with the intent that I should fix things
properly, not just let them simmer ... I headed down another path in
the last couple of hours trying to solve this properly.

Anyway given that I want to instead ripple exceptions up to the caller
instead ... I noticed part of the module face code introduced this
concept of 'multiline' methods on exceptions, and looking at what has
been written a lot of wrapping code in the faces 'application' bits
has been added to coerce these into a results hash so the Face can
render them.

I can't help but think this is extra typing though, and I'd rather
that if I raise an exception in the 'when_invoked' block the message
gets rendered on its own, multiline or single line.

I'm sort of swimming in a see of uncertainty regarding the original
aim here for failure in a face - I can gather that a multi-line
variant was experimented on in this code specifically for the module
